Simple, special voltage stabilizing circuit

Simple, special voltage stabilizing circuit:

In some occasions, if a regulated power supply is needed during load operation, it can be used for control, detection and other purposes. Then this circuit appears relatively simple and convenient. Adjusting the ratio of R1 and R2 can change the input voltage of the voltage stabilizing block. The value of C1 is related to the load of the voltage stabilizing output. A

If the unidirectional thyristor is changed to a bidirectional thyristor, the circuit will be simpler. . . B
